This puzzle if very smooth and a controllable speed out of the box. Some people have claimed to have little catches but I have not had any of those. I added some magnets to mine (N42 3x1.5) and it is what I used at my last competition.

This replaced the DaYan for me. I am not the fastest solver (4.5 seconds on average) but this cube was exactly what I have been looking for. Other cubes like the WeiPo just feel a bit too heavy and the light feeling of the XingHen seen to be exactly what I was looking for.
